The formation of spindle shaped hierarchical zinc gallate (ZnGa2O4) architectures was obtained through a simple hydrothermal process without the presence of any surface-active agent. The X-ray powder diffraction pattern indicated the formation of well crystallised in ZnGa2O4. The field emission scanning electron microscopy and high resolution transmission electron microscopy images showed that the spindle shaped hierarchical ZnGa2O4 architectures were constructed by octahedral ZnGa2O4. A feasible formation mechanism for the obtained spindle shaped ZnGa2O4 structure was proposed. The photocatalytic performance of the obtained ZnGa2O4 architectures was tested by the degradation of methylene blue under UV light irradiation. The result shows that spindle shaped ZnGa2O4 architectures have good photocatalytic performance.
